Ok, so editing is apparently not my strong suit, lol. I hate it when equipment comes with those on the cord, you have no way of verifying if the equipment is bleeding current to ground or if the gfci is bad (which can happen, especially since they aren't the highest of quality). I poked around on the intex site and they dont even list the power supply as a replacement part. The manual says the 8110 uses almost twice the current of the 7110 so basically you probably cant swap them.
Dang, that's not good. Swapping them isn't going to work. Time for some bleach!
